Patent Application
20220247542
The present application relates to the field of communications, for example, to a resource activation method and apparatus, a storage medium and an electronic apparatus.
In the new radio (NR) access technology network, the downlink semi-persistent resource used by the user equipment (UE) is activated by two steps. Firstly, a configuration is partially issued by the network through a radial resource control (RRC) signaling. The configuration will not be activated after being issued. Then, the downlink semi-persistent resource is activated, that is, the UE activates the downlink semi-persistent resource upon receiving the downlink control information (DCI) new data indicator (NDI)=0 of the physical downlink control channel (PDCCH).
In a case where the interface (i.e., Uu interface) between the UE and the universal mobile telecommunications system terrestrial radio access network (UTRAN) (the radio interface between the UTRAN and the UE) is relatively low in reliability, the UE blindly detects the DCI of the PDCCH, so the UE may miss the DCI corresponding to the PDCCH, resulting in the failure to activate the downlink semi-persistent resource. As a result, the network considers that the downlink semi-persistent resource of the UE has been activated, but the UE has not activated the downlink semi-persistent resource, resulting in state inconsistency between the network and the UE. In this case, the UE cannot receive the downlink data subsequently delivered by the network, and the network cannot distinguish the reason why the UE does not receive the downlink data. For example, the network cannot determine whether or not the failure of the UE to receive downlink data is caused by abnormal downlink decoding or non-activation of downlink semi-static resources, which increases the complexity of network processing. In addition, in order to restore the link, the network may re-activate the downlink semi-persistent resource or reconfigure the resource, so that the delay of downlink data delivery is invisibly increased. For example, if the network service is a packet internet groper (PING) packet and the delay of the PING is set to be very short, the PING packet will be lost, thereby affecting the service performance. On the other hand, in a case where there exist both a persistent configuration and a dynamic configuration, if the network has perceived that the UE has a downlink semi-persistent resource, the dynamic downlink resource may not be configured, thus causing the downlink service to be blocked. Still on the other hand, when the network deactivates the downlink semi-persistent resource of the UE again, since the UE does not perceive the activation, the network cannot receive a deactivation acknowledgement from the UE in the physical layer, resulting in the retransmission of the deactivation message. The longer the retransmission time is, the longer the downlink resources are occupied. Thus, the utilization efficiency of downlink resources is reduced.
There are no solutions to the problem that the service cannot be normally carried out in the related art due to the inconsistent perceptions of the network and the UE on whether or not the downlink semi-persistent resource is activated.
Embodiments of the present application provides a resource activation method and apparatus, a storage medium and an electronic apparatus, in order to at least solve the problem that the service cannot be normally carried out in the related art due to the inconsistent perceptions of the network and the UE on whether or not the downlink semi-persistent resource is activated.

The embodiments of the present application will be described below with reference to scenarios.
In an NR network, the network issues a signaling for indicating activation of downlink semi-persistent scheduling (DL SPS), for example, issuing a DCI of a PDCCH. In a case where the Uu interface (i.e., an air interface) is relatively low in reliability, since the UE blindly detects the DCI of the PDCCH, the UE may miss the DCI corresponding to the PDCCH, so that the downlink semi-persistent resource cannot be activated. However, the network side considers that the downlink semi-persistent resource of the UE has been activated, resulting in inconsistent perceptions of the network and the UE on whether or not the downlink semi-persistent resource has been activated.
In order to ensure consistent perceptions of the network and the UE on whether or not the downlink semi-persistent resource is activated, two schemes are provided in the embodiment of the present application.
In an implementation, after the network side issues the DCI of the PDCCH to instruct the UE to activate the downlink semi-persistent resource, if the UE has activated the downlink semi-persistent resource, the UE may return an acknowledgment (ACK) message in the physical layer, and the UE may return this ACK message on uplink control information (UCI) of the physical uplink control channel (PUCCH). An uplink bandwidth part (UL BWP) on which the UE transmits the ACK message should correspond to a downlink bandwidth part (DL BWP) on which the network side transmits the DL SPS to the UE.
If the network side receives the corresponding ACK message, it is determined that the UE has activated the downlink semi-persistent resource; and if the network side does not receive the ACK message, N retransmissions may be performed to ensure normal activation of the UE.
In an implementation, after the network side issues the DCI of the PDCCH to instruct the UE to activate the downlink semi-persistent resource, if the UE has activated the downlink semi-persistent resource, the UE returns a medium access control control element (MAC CE) (e.g., configured grant confirmation medium access control control elements) message to the network side. Upon receiving the MAC CE message, the network side confirms that the downlink semi-persistent resource has been activated. The MAC CE message may further carry an identifier for indicating an activation object. For example, if a downlink (DL) cell is filled in the MAC CE message, the network side can determine that the activation object is a downlink semi-persistent resource configuration through the MAC CE message. For example, if an uplink (DL) cell is filled in the MAC CE message, it is indicated that the activation object is an uplink persistent resource.
By the above solutions, the consistent perceptions of the network and the UE on whether or not the downlink semi-persistent resource is activated can be ensured, the complexity of network processing can be reduced, and the reliability of services can be improved.
At step S610, a network side issues a DL SPS configuration through an RRC signaling.
At step S620, the network side activates the DL SPS for N times, and it is determined whether or not the number of times of activating the DL SPS by the network side exceeds N; if the number of times of activating the DL SPS by the network side exceeds N, step S630 will be executed; and if the number of times of activating the DL SPS by the network side does not exceed N, step S640 will be executed, where N is a positive integer and may be set in advance.
At step S630, a flow when a wireless link is abnormal is executed. For example, a prompt, an alarm or the like may be given out.
At step S640, the network side activates the DL SPS by issuing PDCCH DCI.
At step S650, it is determined whether or not the UE blindly defects the DCI successfully; if the UE blindly detects the DCI unsuccessfully, step S660 will be executed; and if the UE blindly detects the DCI successfully, step S670 will be executed.
At step S660, if the UE blindly detects the DCI unsuccessfully and the network side does not perceive an ACK message for a period of time, it is considered that the UE does not activate the DL SPS.
At step S670, if the UE blindly defects the DCI successfully, the UE returns an ACK message on the PUCCH UCI.
At step S680, the network side receives the ACK message indicating that the DL SPS has been activated; and the perceptions of the network side and the UE on whether or not the downlink semi-persistent resource is activated are kept synchronous.
At step S710, a network side issues a DL SPS configuration through an RRC signaling.
At step S720, the network side activates the DL SPS for N times, and it is determined whether or not the number of times of activating the DL SPS by the network side exceeds N; if the number of times of activating the DL SPS by the network side exceeds N, step S730 will be executed; and if the number of times of activating the DL SPS by the network side does not exceed N, step S740 will be executed, where N is a positive integer and may be set in advance.
At step S730, a flow when a wireless link is abnormal is executed. For example, a prompt, an alarm or the like may be given out.
At step S740, the network side activates the DL SPS by issuing PDCCH DCI.
At step S750, it is determined whether or not the UE blindly defects the DCI successfully; if the UE blindly detects the DCI unsuccessfully, step S760 will be executed; and if the UE blindly detects the DCI successfully, step S770 will be executed.
At step S760, if the UE blindly detects the DCI unsuccessfully and the network side does not perceive an MAC CE message for a period of time, it is considered that the UE does not activate the DL SPS.
At step S770, if the UE blindly detects the DCI successfully, the UE transmits an MAC CE message (i.e., configured grant confirmation MAC CE message) on the corresponding UL BWP), where the MAC CE message carries a directional label (DL) to indicate that the DL SPS has been activated.
At step S780, the network side receives the MAC CE message indicating that the DL SPS has been activated; and the perceptions of the network side and the UE on whether or not the downlink semi-persistent resource is activated are kept synchronous.
In the embodiment of the present application, the “network”, “network side” and “network device” have the same meaning and all refer to a network device that interacts with the UE, for example, a next generation Nodeb (gNB).
